TL;DR: In this paper , the collection and conservation of soybean wild relatives and the dissection of their genomic features will accelerate soybean breeding and facilitate sustainable agriculture and food production, which is a major obstacle to soybean improvement.
Abstract: Abstract Genetic diversity is a cornerstone of crop improvement, However, cultivated soybean ( Glycine max ) has undergone several genetic bottlenecks, including domestication in China, the introduction of landraces to other areas of the world and, latterly, selective breeding, leading to low genetic diversity the poses a major obstacle to soybean improvement. By contrast, there remains a relatively high level of genetic diversity in soybean’s wild relatives, especially the perennial soybeans ( Glycine subgenus Glycine ), which could serve as potential gene pools for improving soybean cultivars. Wild soybeans are phylogenetically diversified and adapted to various habitats, harboring resistance to various biotic and abiotic stresses. Advances in genome and transcriptome sequencing enable alleles associated with desirable traits that were lost during domestication of soybean to be discovered in wild soybean. The collection and conservation of soybean wild relatives and the dissection of their genomic features will accelerate soybean breeding and facilitate sustainable agriculture and food production.

TL;DR: In this article, the SNP molecular markers related to fiber strength of an upland cotton 25# chromosome were used for molecular marker-assisted selection, so that the breeding period can be greatly shortened, and the breeding efficiency of the cotton fiber strength can be increased.
Abstract: The invention relates to SNP molecular markers related to fiber strength of an upland cotton 25# chromosome The invention belongs to the technical field of cotton molecular breeding and discloses the SNP molecular markers related to fiber strength of the upland cotton and detection and application thereof The SNP molecular markers are obtained by taking a stable RIL group of cotton as a material by means of a genome re-sequencing method The SNP markers disclosed by the invention are used for molecular marker-assisted selection, so that the breeding period can be greatly shortened, and the breeding efficiency of the cotton fiber strength can be increased

TL;DR: Up-to-date information on the progress made in last 5 years in peanut genomics is provided with a particular focus on the latest genomic findings, tools, and strategies employed in genome sequencing, transcriptomics, trait mapping, and molecular breeding approaches.
Abstract: Peanut is an important oilseed and legume crop with global relevance to food and nutritional security in addition to source of income to millions of stallholder farmers of the Sub-Saharan Africa and Asia. Low genetic diversity in cultivated genepool and ploidy differences between different genepools have been the two important genetic bottlenecks hampering use of molecular breeding approaches for peanut improvement. Nevertheless, recent advances in genomics research have elevated the status of peanut from “resource-poor” to “genomic resource-rich” crop and therefore, it is an obligation to the peanut research community across the world to adopt a holistic approach including use of genomics information and tools in crop improvement programs. In this context, this book provides up-to-date information on the progress made in last 5 years in peanut genomics with a particular focus on the latest genomic findings, tools, and strategies employed in genome sequencing, transcriptomics, trait mapping, and molecular breeding approaches. This chapter by providing an overview of the contents of the book presents a big picture on the current status of peanut genome and allied information and its potential applications for peanut improvement.
